Airthings View Plus review
Airthings View Plus (2960) Radon & Indoor Air Quality Monitor
By Tom Calder
The only monitor here that measures radon, PM2.5 and CO2 together, and the only Airthings with a proper numeric display alongside the app and web dashboard. It has no carbon monoxide sensor, so it changes nothing about your need for a certified alarm. Airthings also states the CO2 and VOC readings take around seven days to settle, so judge it in week two rather than week one.
- Best for
- One device covering radon, particulates and CO2 in the same room, with a screen you can actually read.
- Skip it if
- You only care about ventilation

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Seven sensors in one unit, including radon, PM1/PM2.5 and CO2
- 2.9in e-ink screen means you read it in passing rather than opening an app
- Runs on 6x AA for a claimed two years, or on USB-C mains as a SmartLink hub for Wave devices
Worth knowing
- No carbon monoxide sensor at all — it is not, and cannot be, a CO alarm
- Airthings states CO2 and VOC readings need roughly seven days to settle, so early numbers mislead
- UK pricing swings widely for the same unit depending on retailer

Our review
A battery-powered monitor with seven sensors and a 2.9-inch e-ink screen that reads radon, fine particles, CO2, airborne chemicals, temperature, humidity and pressure, and sends the lot to an app over Wi-Fi. Radon is the point: the one hazard here you cannot see or smell, and the one for which UKHSA sets an Action Level. It suits a household in a radon-affected area that wants a continuous record rather than a single test.
What it measures and how well
Radon is counted in a passive diffusion chamber by alpha spectrometry, sampled hourly across 0 to 20,000 Bq/m³. Airthings puts typical accuracy, after 30 days of continuous running at 200 Bq/m³, at ±10% for a seven-day average and ±5% for a two-month average. UKHSA's Action Level is 200 Bq/m³ and its Target Level 100, and the standard UK test is two detectors left for three months, so treat the first fortnight as a warm-up. PM2.5 comes from a laser particle counter covering 0.3 to 10 microns, with a stated error of ±(5 µg/m³ + 15%) below 150 µg/m³. CO2 uses an NDIR cell over 400 to 5,000 ppm, rated at ±50 ppm ±5% on the spec sheet. The VOC sensor needs about seven days to settle.
In a British home
Airthings says to place it at breathing height, 110 to 170 cm, standing or wall-mounted no higher than 2 m, and at least 90 cm from windows, doors and vents. For radon, UKHSA's own test uses a living room and a bedroom, so start there. The CO2 reading doubles as a ventilation gauge: HSE's guidance is that readings consistently above 1,500 ppm in an occupied room indicate poor ventilation. The PM2.5 figure shows what frying, a wood burner or a smoky evening outside does indoors, and the humidity trace is the early warning for condensation and mould. It connects to 2.4 GHz Wi-Fi only, with Bluetooth used just for setup.
How it compares
The Airthings Wave Plus covers radon, CO2 and VOCs but has no particle sensor and no screen, so you wave a hand for a glow. The Aranet4 Home is the better pure CO2 meter, with a tighter stated accuracy of ±(30 ppm + 3% of reading) and years from two AA cells, but measures nothing else and has no Wi-Fi. The Amazon Smart Air Quality Monitor adds a carbon monoxide reading, though Amazon says it is not a certified CO alarm, and it drops CO2 and radon and must stay plugged in. See the comparison for the rest.
Living with it
Six AA batteries come pre-installed and Airthings claims up to two years from them; a USB-C cable is included and powering it that way also makes it a SmartLink hub for Wave devices. The screen shows four values of your choosing, and a motion-activated glow gives a green, yellow or red summary. The app and web dashboard hold the history; Alexa, Google, IFTTT and Homey are supported, Apple HomeKit is not. It is 17 by 9 by 3.3 cm and 360 g. Operating range is 4 to 40°C and humidity up to 85% non-condensing, and Airthings warns that very high humidity can permanently damage the radon sensor, so bathrooms are out. The standard warranty is 12 months, extended free to five years if you register within 30 days.
What it does not do
There is no carbon monoxide sensor and nothing here sounds an alarm. A home with a boiler, gas hob, open fire or wood burner still needs a certified CO alarm; our guide to carbon monoxide poisoning symptoms explains why. For a formal radon figure, the UK standard remains a pair of passive detectors left for three months; use the View Plus to watch the trend and to check that any remediation keeps working.
Our verdict
Buy it if you live where radon is a known issue and you want the gas, the particles and the stale-air reading on one screen you glance at daily. Look elsewhere if ventilation is your only question, because the Aranet4 answers it more precisely, or if your home is not in a radon-affected area, since radon is the main reason to choose this one over simpler monitors.

Who shouldn't buy this
Don't buy it if you only care about ventilation — the Aranet4 Home measures CO2 more accurately and costs less.

Does the Airthings View Plus detect carbon monoxide?
No. It has no CO sensor and no siren. A certified carbon monoxide alarm is still required wherever fuel is burned indoors, whatever the View Plus is showing.
How long does the View Plus take to give a reliable radon reading?
Airthings states its typical accuracy after 30 days of continuous measuring: ±10% on a seven-day average and ±5% on a two-month average. It also says the CO2 and VOC sensors take around seven days to calibrate.
How long do the View Plus batteries last?
Airthings claims up to two years from the six AA cells, depending on the sensor interval and Wi-Fi router. Plugged in over USB-C it runs indefinitely, samples more often and acts as a hub for Wave monitors.
What radon level is too high in a UK home?
UKHSA recommends reducing radon where the long-term average exceeds 200 Bq/m³, the Action Level, and aims for 100 Bq/m³, the Target Level, when remediating or building. The View Plus reports in the same units.
